I screwed up.
I knew that the end of May was when the Zoobridge was completed and opened to traffic.
In the ‘Obituary’ I wrote for the bridge following its final closing on March 29th, I even noted that it was opened for pedestrian use as of May 27, 1908. Nonetheless, my brain defaulted to assuming the date of completion was May 30, 1908.
Hence I spent all May 26, 2017 watching the removal crews attempting to pull the old bridge off its foundations but never bothered to mention the anniversary until I got home.
I had been going to make a little bet that the bridge would find a way to hold out till its ‘birthday’ and wanted to verify the date. I won my little bet, it got to stay put.
